A leakage magnetic flux will occur at the shaft end of the servo motor equipped with an electromagnetic
brake. Note that chips, screws, etc. are attracted.
1.4 Servo motor shaft shapes
In addition to the straight shaft, the key shaft and D cut shaft are available.
The key shaft and D cut shaft cannot be used in frequent start/stop applications.
Since we cannot warrant the servo motor against fracture and similar accidents attributable to a loose key,
use a friction coupling, etc. when coupling the shaft with a machine.
The shaft shape of the standard servo motor changes depending on the series and capacity. Refer to the
chapter of the servo motor series.
The key shaft (with single pointed key) applies to only the geared servo motor for high precision application.
